Spark Plug Patents (Class 451/77)
  • Patent number: 9925642
    Abstract: Wet abrasive blasting systems are described that have a slurry piping system and a gas piping system that have pipes and other piping components, such as valves and regulators, that have a more consistent internal cross-sectional area than conventional wet abrasive blasting systems. The more consistent flow area provides astonishing improvements in blasting efficiency and consistent and predictable slurry flow rates.
